Known Issues with Nginx Installation
connect() to unix:/home/user/.phpbrew/php/php-7.1.4/sbin/php-fpm failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: host.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/home/user/.phpbrew/php/php-7.1.4/sbin/php-fpm:", host: "host.com"

How to solve the issue:

1. Open /home/user/.phpbrew/php/php-7.1.4/etc/php-fpm.d/www.conf
2. Replace

user = nobody
group = nobody

with

user = www-data
group = www-data

3. Uncomment follow strings and specify user and group:

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

Run php-fpm
sudo ~/.phpbrew/php/php-7.1.4/sbin/php-fpm -R
